IMPROVEMENT IN MACHINES FOR CRUSHING COKE.

Specification forming part of Letters Patent No. 160,765, dated March16, 1875; application filed June 18,1874.

To all whom it may concern:

Be it known that 1, CHARLES GLAZIER, of the city of Indianapolis, countyof Marion and State of Indiana, have invented an Improved Machine forCrushing Coke, of which the following is a specification:

The object of my invention is to provide a means for easily and rapidlybreaking coke into small pieces of approximately uniform size, andseparating the dust therefrom for the purpose of adapting it to use inthat class of stoves known as base-burnin g or magazine stoves.

My invention consists in the arrangement and combination of an adjustingdevice and one of a pair of metallic jaws, one of which is stationaryand the other movable and adjustable, and a sitting device, as hereinmore fully described.

The accompanying drawing illustrates my invention.

FigureL-Ais a suitably-constructed frame, to which is attached astationary jaw, a, and a vibrating frame, B, carrying a second jaw, e,and having a bearing on the rod 0. The frame B is so arranged inrelation to the frame A that the jaws a and e are placed opposite eachother with a small space between them at their lower edges, and a widerspace above. The lower edge of the jaw e is made movable and adjustablein relation to the frame B by means of the screws 6 z', for the purposeof regulating the size of the pieces of coke passing through. To theupper end of the frame B a connecting-rod, r, is attached, by means ofwhich, through its connection with the crank-shaft 0, a vibratory motionis given to the frame B, and the jaw e is made to alternately approachand recede from the jaw a. To the lower ends of the frame B, a sieve, s,is attached in such position as to receive the coke as it leaves thejaws to and e and conduct it to the front of the machine.

The operation of m device is as follows:

The coke in large pieces, being thrown into the hopper-shaped openingformed by the jaws to and e, is crushed as the jaws are brought nearertogether. As the jaws separate the pieces fall into anarrower portionandare again crushed, the ratchet-shaped teeth or corrugations on the jawsserving to prevent them from slipping upward, and the operation beingrepeated until the pieces are small enough to fall through the spacebetween the lower edges of the jaws onto the screen or sieve s, which,having an inclined surface and being constantly agitated by thevibrations of theframe B to which it is attached, effectually separatesthe finer particles and delivers the coke clean and of a uniform size,which size may be controlled at will by the set-screws ii.

I am aware that crushing-machines have heretofore been made, in whichthe crushingjaws vibrate and have a tapering space between them, and Ido not claim such an arrangement; but- I claim as my invention Thecombination of the adjust-a blej aw 6, setscrews it, frame B, and sieves, all constructed and arranged substantially as and for the purpose setforth.

CHARLES GLAZIER.
